Vice City: Multiplayer

This Squirrel code defines the `When` class and `when` function, enabling conditional logic functionality. The `When` class includes methods like `is` (equal to) and `isNot` (not equal to). If conditions are met, corresponding actions are executed and results are recorded, with only the first matching action triggered. Otherwise, all non-matching cases are handled, and the final result is returned.

class When {
    value = null;
    found = false;
    result = null;

    constructor(value) {
        this.value = value;
    }

    function is(expected, action) {
        if (!found && value == expected) {
            found = true;
            result = action();
        }
        return this;
    }

    function isNot(expected, action) {
        if (!found && value != expected) {
            found = true;
            result = action();
        }
        return this;
    }

    function isType(typeName, action) {
        if (!found && typeof value == typeName) {
            found = true;
            result = action();
        }
        return this;
    }

    function isNull(action) {
        if (!found && value == null) {
            found = true;
            result = action();
        }
        return this;
    }

    function inRange(min, max, action) {
        if (!found && value >= min && value <= max) {
            found = true;
            result = action();
        }
        return this;
    }

    function match(condition, action) {
        if (!found && condition(value)) {
            found = true;
            result = action();
        }
        return this;
    }

    function otherwise(action) {
        if (!found) {
            result = action();
        }
        return result;
    }
}

function when(value) {
    return When(value);
}

Here is an example
local x = 65;
local result = when(x)
    .isNull(@()"is Null")
    .isType("float", @()"Not Float")
    .is(100, @()"Max")
    .inRange(0, 35, @()"0~35")
    .inRange(35, 70, @()"35~70")
    .match(@(v) v * 2 > 150 && v < 80, @()"75~80")
    .otherwise(@()">80");

print(result); // out 0~35
